1 Claim. (Cl. 1269) This invention, relates to utility stoves, and more particularly to an improved stove designed for outdoor use, which can be inexpensively constructed and made conveniently collapsible to occupy limited space in storage and transportation. I

This improved utility stove, designed to serve the comfort and convenience of campers 'and sportsmen, can be inexpensively fabricated from relatively light gauge sheet metal, is light in weight, and can be carried and transported in collapsed condition as a compact, unitary package. When the stove is to be used, the collapsed and nested parts thereof can be erected and assembled in approximately a minute or less time to provide a highly eiiicient heating unit wherein combustible fuel such as coal, charcoal, wood or similar fuel, may be burned upon a fire grate member associated therewith.

This improved stove is also provided with a top panel which may be readily adjusted to control the air draft, and thereby control the rate of fuel combustion, as desired. The adjustable top panel also provides a hot plate upon which a cooking utensil or the, like may be supported.

The improved stove is also provided with a receptor pan in which the burned ash from the superimposed fire grate is collected.

This improved utility heating unit may be constructed in any desired size ranging from approximately four inches in width and breadth and eight inches high, to such larger sizes as may best suit the convenience of the camper or sportsman. .The unit may be provided with aremovable carrying handle whereby the fully assembled unit may be conveniently transported. The parts forming this utility unit are so constructed that they may be conveniently and quickly detached from each other and nested together in a compactimanner to provide an as sembled package less than 1 inch thick and of limited area.

Fig. 10 is a perspective view of the stove forming parts as they appear when nested together in a compact package for convenient storage and stove is formed from a plurality of shaped. sheet metal parts comprising a pair of oppositely arranged support panels lll on which the pair of suspended panels 20 are hung to provide a fourwalled enclosure. A sheet metal grate member 3!] is positioned within the walled enclosure formed by the support panels Ill and the sus pended panels 29. The stove unit also includes an ash receptor pan ll! which additionally serves as a base upon which the support panels Ill are seated. A top panel 5!) of sheet metal shaped to telescope over the upper ends of the enclosure forming panels It] and 20, provides a hot plate upon'which food may be broiled, or a cooking utensil supported.

edges thereof. The lower edge i3 of the paired support panels I are designed to seat upon the base wall 4! of a receptor pan 40. The receptor pan 40 has a pair of upstanding flanges 42 which are sprung slightly inwardly so as to exert a frictional grip against the flanges l2 of the support panels In as seated on the base wall 4! of the receptor pan. The receptor pan flanges 42 may be provided'with suitable blisters or pimples t3, complementary to blisters or pimples is formed in the panel flanges 12 adjacent the lower ends thereof, to insure positive frictional attachment of the support panels I!) to the receptor pan 40.

Each of the paired suspended panels 28 are of somewhat less height than the support panels Ill, and are hung from the spaced flanges I2 of the paired support panels H) in space relation to the receptor pan 8, as shown more particularly in Fig. 1. Each suspended panel 20 comprises a wall forming section 2| presenting a pair of projecting metal buttons 22 along each vertical side edge thereof; The buttons 22 are designed to be inserted into complementary bayonet slots I formed in the adjacent overlying flanges E2 of the support panels l0. Each suspended panel 28 is also provided with an inturned flange 23 extending horizontally along the lower edge thereof to provide a support for the grate member 39.

The suspended panels are detachably connected to the space support panels it) by inserting each lock button 22 through the enlarged head portion i5 of the adjacent bayonet slot, and then lifting the suspended panels 2%] upwardly so that each lock button 22 will be retained in the contracted neck portion l5 of its associated bayonet slot. When thus assembled, the upper edge 24 of the suspended panels 20 will be substantially in the same plane as the upper edge It of the support panels, as shown more particularly in Fig. l. The suspended panels 20 may be detachably locked in suspended position by the provision of latch dogs H. Each latching dog I? is hinged as by pivot pin 8 to the flange i2 of the support panel Ill. The latch dogs H are positioned directly below the lower edge of the suspended panels 20 as mounted in assembled position, and are designed to be swung upwardly with the cam edges ll thereof in frictional camming engagement with the under face of the inturned flanges 23 of the adjacent suspended panel 28. When the latch dogs I! are in up-swung position, as shown in phantomlines in Fig. 2, the suspended panels 28 are supported thereby in rigidly assembled and locked position. The latch dog l'i' may, however, be down-swung as desired to disconnect the enclosure forming panels In and 20.

The grate member 38 comprises a flat plate of sheet metal having a series of air draft holes 3! punched therein. The grate member 30 is of generally rectangular shape, and of a size so that it may be dropped into the erected enclosure forming panels H! and 20, so as to seat upon the inturned flanges 23 of the suspended panels 2%, as shown more particularly in Fig. 3. As thus supported, the grate member 38 is spaced above the base wall 4! of the receptor pan 40 so as to permit draft air to be drawn through the open space above the upstanding flanges 42 of the receptor pan All, through the grate openings 30, and into the fire chamber defined by the assembled enclosure forming panels I!) and 20. A series of air openings 25 may also be punched through the wall forming section 2| of the suspended panel 20 to insure adequate air draft.

The top panel is formed of a light gauge pensively formed sheet metal parts which can be manufactured at very low cost. The stove may be assembled in a matter of a minute or less by attaching the suspended panels 29 to the support panels ill, and locking the suspended panel 28 in position by up-swinging the latch dogs 1?. The lower ends l3 of the support panels iii are inserted into the receptor pan J9 and detachably secured thereto by the cooperating male and female pimples i l and 33 associated with the support panels i9 and the receptor pan ii respectively. The grate member 32, when dropped into the enclosure formed by erected panels 58 and 23, will automatically seat in rest position on the inturned flanges 22 of the suspended panels 29.

Wood kindling placed upon the enclosed gra member 36 may be conveniently lighted through the upper end of the enclosure forming panels, and additional fuel such as charcoal, coke, coal or wood added to produce the desired heat. The top panel 58 mounted in position on the enclosure forming panels if! and 28, may be moved laterally as desired to provide a draft opening a which insures combustion of the fuel at the desired rate. The plate section of the toppan l 58 also provides a hot plate on which food may be fried or broiled, or upon which a cooking utensil may be supported. This improved utility stove may also be provided with a suitable carrying handle 6!! formed of wire, as shown in 9. The handle 60 is provided with hook portions (it designed to be detachably inserted into suitable openings 29 formed in the adjacent upper end of the suspended panels 28. Thus the entire stove unit may be lifted and carried around at the camp location.

This improved utility stove is so shaped and formed as to permit the detachable parts thereof to be assembled into a flat and compact package, as shown in Figs. 10, 11 and 12, to facilitate storage and transportation thereof to and from the camp site. The suspended panels 2% are so shaped and formed that they can be snugly nested within the wall forming flanges E2 of one of the support panels In, which thus serves as a tray member, as shown more particularly in Figs. 11 and 12. There is ample room between the flanges l2 of the tray forming support panel IE to also receive the flat grate member Efrand the carrying handle 60. When the suspended panels 20 and the grate member 35 have been nested between the flanges H of the tray forming support panel 10, the other support panel til serving as a cover for the package, is telescoped together with the tray forming support panel, with the flanges l2 of the support panels arranged in overlapped relationship as shown in Fig. 12.

The flanges 42 of the receptor pan it are so spaced as to permit the receptor pan 46 to be snugly telescoped over one of the package forming support panels Id. The flanges 32 of the receptor pan have a slight inward camber or spring, so as to frictionally embrace the outside snugly seating over the outside face of adjacent wall section II adjacent the support panel. Likewise, the flanges 52 of the top panel 50 are so spaced as to snugly telescope over the other support panel II), with the inwardly sprun flanges 52 thereof frictionally gripping and embracing a section of the flanges 42 of the receptor pan 40, as shown in Figs. 10 and 11. Thus the top panel 50, when in telescoped position, serves to grip and clamp the telescoped receptor pan 40 and the covering and tray forming support panels l together in a flat and compact assembly which can then be carried and transported as a unitary package.

- This improved utility stove admirably serves the needs of sportsmen and campers by reason of its novel features of construction, which permits all the component parts thereof to be nested together in a compact rectangular package of minimum cubicle volume, adapted to be carried in the pocket of the camper or sportsmen. The

component parts of the stove are inexpensive to I fabricate, and provide a utility stove unit which can be manufactured and sold at relatively low cost. This improved stove unit is further designed for erection and assembly from package form in a matter of a minute or less, and when the parts thereof have been assembled and locked together, a sturdy and rigid heating and cooking unit is provided which admirably serves the comfort and convenience of the outdoor camper and sportsman.

While certain novel features of the invention have been disclosed herein, and are pointed out in the claim, it will be understood that various omissions, substitutions, and changes may be made by those skilled in the art without departing from the spirit of the invention.

What is claimed is:

A knock-down campers utility stove comprising a pair of sheet metal support-panels each presenting a wall portion and side flange portions extending from the wall portion, a pair of opposite sheet metal suspension panels, means for detachably connecting said suspension panels to said support panels to provide a walled enclosure, said connecting means comprising heat resistant headed rivets spaced along the opposite side margins of each suspension panel operative to removably interlock into corresponding bayonet slots formed in the flange p tions of said support panels, a receptor pan providing a base upon Which said support panels are supported, said receptor pan having flange portions designed to receive and resiliently grip the lower ends of said support panels when seated within the receptor pan, a removable grate member fittable within the walled enclosure formed by the connected support panels and suspension panels, each of said suspension panels having an inturned flange adjacent the lower edge thereof providing a rest support for said grate member in spaced relation to said receptor pan, said suspension panels being of shorter length than said support panels providing a grate updraft passage therebelow, and a top panel adapted to be removably supported on the upper ends of said connected support panels and suspension panels providing a hot plate for the assembled stove.
